c181840c93 Consolidate non cancellable close call 
This patch consolidates all the non cancellable close calls to use
the __close_nocancel{_nostatus} identifier.  For non cancellable targets
it will be just a macro to call the default respective symbol while on Linux
will be a internal one.

Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE
namespace.

Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu.

af7f7c7ec8 network: recvmsg and sendmsg standard compliance (BZ#16919) 
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen
to be of size int and socklen_t respectively.  However Linux defines it as
both size_t and for 64-bit it requires some adjustments to make the
functions standard compliance.

This patch fixes it by creating a temporary header and zeroing the pad
fields for 64-bits architecture where size of size_t exceeds the size of
the int.

Also the new recvmsg and sendmsg implementation is only added on libc,
with libpthread only containing a compat symbol.

Tested on x86_64, i686, aarch64, armhf, and powerpc64le.

2eecc8afd0 Terminate process on invalid netlink response from kernel [BZ #12926] 
The recvmsg system calls for netlink sockets have been particularly
prone to picking up unrelated data after a file descriptor race
(where the descriptor is closed and reopened concurrently in a
multi-threaded process, as the result of a file descriptor
management issue elsewhere).  This commit adds additional error
checking and aborts the process if a datagram of unexpected length
(without the netlink header) is received, or an error code which
cannot happen due to the way the netlink socket is used.
